A power tool is a tool that is actuator by an additional engine and mechanism other than the solely manual labour used with . The most common types of power tools use . Internal combustion engines and compressed air are also commonly used. Tools directly driven by working animal are not generally considered power tools. Power tools can produce large amounts of particulates, including ultrafine particles. Airborne particulate matter is a Group 1 carcinogen.
Uses
Using hand and power tools to cut plastic materials during construction activities can generate microplastics. Airborne microplastics is a type of particulates. Further studies are needed "on the different types of cutting tools and their associated MP production".
Classification
Stationary power tools for metalworking are usually called . The term machine tool is not usually applied to stationary power tools for woodworking, although such usage is occasionally heard, and in some cases, such as drill presses and , exactly the same tool is used for both woodworking and metalworking.
Health impact
Airborne particulate matter is a Group 1 carcinogen. Particulates are the most harmful form (other than ultra-fines) of air pollution as they can penetrate deep into the lungs and brain from blood streams, causing health problems such as heart disease, lung disease, and death. There is no safe level of particulates. A 2013 study concluded that "particulate matter air pollution contributes to lung cancer incidence in Europe". Worldwide, exposure to PM contributed to 4.1 million deaths from heart disease, stroke, lung cancer, chronic lung disease, and respiratory infections in 2016. Overall, ambient particulate matter is one of the leading risk factor for premature death globally.
Many construction tasks create dust. High dust levels are caused by one of more the following:
- equipment – using high energy tools, such as cut-off saws, grinders, wall chasers and grit blasters produce a lot of dust in a very short time
- work method – dry sweeping can make a lot of dust when compared to vacuuming or wet brushing
- work area – the more enclosed a space, the more the dust will build up
- time – the longer you work the more dust there will be
- using power tools to cut, grind, drill or prepare a surface
- sanding taped drywall joints
- dry sweeping
Some industry standards on the size and amount of dust emitted by power tools exist, though it appears that they are not widely known or used globally. Knowing that dust is generated throughout the construction process and can cause serious health hazards, manufacturers are now marketing power tools that are equipped with (e.g. HEPA vacuum cleaners) or integrated water delivery system which extract the dust after emission. However, the use of such products is still not common in most places. As of Q1 2024, petrol powered tools are banned in California.
Using power tools without Earmuffs over a long period of time can put a person at risk for hearing loss. The U.S. National Institute for Occupational Safety and Health (NIOSH) has recommended that a person should not be exposed to noise at or above 85 decibel, for the sake of hearing loss prevention. Most power tools, including , , , and , operate at Sound intensity above the 85 dB limit, some even reaching over 100 dB. NIOSH strongly recommends wearing hearing protection while using these kinds of power tools.
In the early 1930s, companies started to experiment with housings of thermosetting polymer plastics. In 1956, under the influence of Hans Erich Slany, Robert Bosch GmbH was one of the first companies to introduce a power tool housing made of glass filled nylon.
Examples of battery differences include the battery technologies themselves, with nickel-metal hydride (NiMH) and nickel–cadmium batteries (Ni-Cd) being common previously, but as of 2021, lithium-ion batteries have become the de facto standard for new power tools. The voltage is one of the most important factors for battery compatibility. In simple terms, a higher voltage rating on the tool often means that the power tool can deliver more power, with all else being equal. Using a battery with the wrong voltage rating may damage the tool, persons, or surroundings. As of 2021, 18-volt battery packs are the de facto standard in new power tools. The ampere-hour, in simple terms, tells something about how long the power tool can operate before it needs to be recharged. If comparing two batteries with the same battery technology and same voltage rating, a battery with twice the amp hour rating should last about twice as long. In practice there may however be some variations to this. Also, batteries with a higher amp hour rating in practice can also often let the power tool deliver a slightly higher peak power due to the ability to deliver a higher current.
Even when using the same battery technology, voltage rating and amp hour rating, the interface of batteries for power tools are often not compatible across different manufacturers, and sometimes also not even within the same brand or product line. There are examples of aftermarket adapters being made so that the user can mix and match batteries between well-known brands, but these often do not fully implement the tools battery safety and monitoring systems and the use is done at the user's own risk.
